Video recorded July 16th, 2016.
As the camera pans about the netted courtyard of an apartment building, two adult birds are seen, one perched at the opening of a nest within the walls. The other on the edge of a lower roof. The squeaking sounds of young birds calling from within the nests can be heard.
There are at least six such nests in the walls of this courtyard. The nests are homes to parents, fledglings and squabs. With six pairs of adults living and reproducing within the walls, there are young squabs present in the nests at any given time of year. The birds here always produce two offspring per clutch. Their eggs require approximately 18 days of tending before hatching. The young fledglings emerge approximately one month after hatching and another clutch of eggs may already be present in the nest at the time the fledglings emerge. The parents within different nests produce eggs at different times. A near-constant procession of young birds exists within the nests of these walls.
This recording was made three days before the seventh attempt by workers to drive birds out of the courtyard and repair the netting overhead. These are active nests routinely interfered with by workers here. An eighth attempt by workers to drive out the birds occurred just yesterday, July 21st, 2016.
These wild birds need help.
Duration 30 seconds. Recorded on an iPhone 4S.
